Questions
Fair answers before you decide
Do the calculators ever cost anything?
No. All six calculators work without an account and stay free. Premium only adds scale to the Pixel workspace and exports.
What happens to my charts if I never upgrade?
They stay yours. Charts and projects on the free account remain editable; premium only lifts size, colour, and export limits.
When does billing open?
After the cloud beta. Join the list below and we will email you before anything is charged — no surprise invoices.
Where is my data stored?
Local projects and charts live on your device. A free account syncs projects to the cloud; images for pixel conversion never leave your browser.
